OK, I have a new torch (holy crap, was that expensive to get into starting from scratch!!) and a "new" old 14 bolt that needs the spring perches cut off to weld on Captainfab's perches. A little concerned about cutting through the axle tube when I do this, so looking for advice from some Jedi torch masters on techniques to prevent a major screwup.
I have read and some guys suggest just cutting through the weld but I don't understand how this can be done without pointing the flame at the axle tube and cutting too far. I'm thinking just aim that flame parallel to the tube and doing the best I can, and finishing with the grinder for a little while to clean it up. I have some 1/4" plate steel that I am going to do a few practice runs on first, just to get a feel for it.

Probably kind of silly, but I just need some reassurance before firing that baby up.
